Flow diagnostics refers to a family of numerical methods that compute quantitative (and detailed) information about the flow behaviour of full 3D reservoir models within a few seconds. The starting point is a flow field, extracted from a previous multiphase simulation or computed by solving a simpli...

Flow diagnostics refers to a family of numerical methods that within a few seconds can compute visually intuitive quantities illuminating flow patterns and well connections for full 3D reservoir models. The starting point is a flow field, extracted from a previous multiphase simulation or computed b...

This work extends the applicability of a class of flow-diagnostic computational tools for interactive visualization and fast simulation approximations to also account for polymer mobility effects. Flow diagnostics, as used here, employ simplifications to the reservoir flow equations to enable comput...

Optimizing objectives of long-term reservoir management typically requires a high number of reservoir simulations. Two important remedies to reduce the runtime (and make the optimization problem manageable) are model reduction/upscaling and efficient computation of gradients. Adjoint methods are gen...

We present MRST–AD, a free, open-source framework written as part of the Matlab Reservoir Simulation Toolbox and designed to provide researchers with the means for rapid prototyping and experimentation for problems in reservoir simulation. The article outlines the design principles and programming t...

Optimizing the objectives of long-term reservoir management typically requires a high number of forward reservoir simulations. Two important remedies to reduce the runtime (and make the optimization problem manageable) are model reduction/upscaling and efficient computation of gradients. Adjoint met...
